BINDER TOOL

Once the binder is created, the edit function is enabled. The edit function is utilized to modify the binder, as illustrated in Figure 6.2.30.

6.2.2.1  CURRENT BINDER

This function is used to display the current binder part. If there are multiple binder parts existing in the current project, the user can click on  button to select the binder part to be modified or operated. Once this button is selected, the Select Binder Part dialog box illustrated in Figure 6.2.31 appears to prompt the user to select a binder part as the current binder.

ADD

Click Add button to pop up the Select Part dialog box and select part as the binder. The binder imported into eta/DYNAFORM is defined as the binder for die face design, and must be added to the binder tools. The program will highlight the selected binder and take it as the binder for the current design.

 

REMOVE

Click this button to delete the selected binder from the list. Only the user defined binder can be deleted. The binder created by the program is not allowed to be deleted.

 

DISPLAY

Click this button to display the selected binder.

 

6.2.2.2  MOVE BINDER

This function allows the user to adjust relative distance between the binder and the part.  The relative distance will affect the draw depth of the part.  Click on the MOVE button to display a dialog box as illustrated in Figure 6.2.32.

Figure 6.2.32  Move binder

 

After Move Direction is selected, the user can select the following methods to move the binder:

1.  Enter a Shift value and click jia or jian button to move the binder.     

2.  Translate the binder by dragging the SLIDER bar.  If the bar is slid to the right, the binder will be translated in the positive direction along the selected axis and vice versa.  Binder Travel

The total binder travel will be displayed in the input field of BINDER TRAVEL.  The program will display the new position of binder on the screen as the user moves the slider.

Binder Shift

The value of the Binder Shift is the shortest vertical clearance between the lowest point of the part along W direction and the binder. When the binder moves along W direction, the binder shift will change accordingly.

Reset

Click Reset button to clear all the travel operations and reset to the initial position.

 

6.2.2.3  ROTATE BINDER

This function allows the user to rotate the binder to an appropriate position. Click on the ROTATE button to display a dialog box as illustrated in Figure 6.2.33. The user can select a rotate axis for rotating binder.

 

Figure 6.2.33  Rotate binder

 

Center of Rotation

After the center of rotation is defined, the program will create a rotation coordinate system parallel to the global coordinate system.

The default center of rotation is the Tipping center. Clicking the Center of Rotation button, the program will pop up a dialog box illustrated in Figure 6.2.34 for the user to select a point as the center of rotation to create a rotation coordinate system parallel to the global coordinate system.

Figure 6.2.34  Input coordinate dialog box

 

Rotate Direction

The binder can rotate about the U, V and W axis of the rotation coordinate system.

After Rotate Axis is selected, the program provides two methods to rotate binder.

1. Enter a Shift value and click jia or jian button to rotate the binder.

2. Rotate the binder by dragging the SLIDER bar.  If the bar is slid to the right, the binder will rotate about the selected axis in a counterclockwise direction and vice versa.

 

Angle

The program will show the amount of rotation angle in the box right below the SLIDER bar. The program will display the new position of binder on the screen as the user moves the slider.

 

Reset

Click Reset button to clear all the rotation operations and reset to the initial position.

NOTE: For parts with symmetry axis, the Rotate Binder function is disabled.

 

6.2.2.4  MESH

This function is used to mesh the binder surface. A dialog box as illustrated in Figure 6.2.35 is displayed.

16

Figure 6.2.35  Set mesh parameters

 

eta/DYNAFORM calculates the default maximum and minimum element size of the mesh based on the shape and size of the binder surface.  The user may enter the desirable value in the input fields.

 

MAX SIZE controls the maximum element size of the mesh.

MIN SIZE controls the minimum element size of the mesh.

 

6.2.2.5  CONTACT CHECK

This function is used to check the contact between reference blank (copy from binder) and punch during drawing. Click this button to display the Contact Check dialog box illustrated in Figure 6.2.36. Copy the existing binder in the position of the initial contact between blank and punch as REFERENCE BLANK and move the reference blank along the stamping direction, as illustrated in Figure 6.2.37.

11 Move the reference blank to the initial contact position.

12 Move the reference blank with a given STEP along the initial contact direction.

13 Move the reference blank with a given STEP along the closing direction.

14 Move the reference blank to the closed position.

 

STEP

Moving step.

 

FROM CONTACT

The distance between reference blank position and the initial contact point.

 

FROM CLOSED

The distance between reference blank position and the closed position.

 

DRAW DEPTH

It is the maximum draw depth between binder and punch. When the die and punch are closed, take the first contact point of reference blank and punch as the reference point. The maximum draw depth is obtained by calculating the draw depths between this reference point and all points on the binder.

 

6.2.2.6  APPLY AND DELETE

APPLY

This function enables the user to create a binder surface and add it to the part C_BINDER.

 

NOTE: If there is an existing C_BINDER part in the current database, eta/DYNAFORM creates a part named BINDER01.  Subsequently, if additional binders are created, BINDERn+1 will be created.  eta/DYNAFORM recognizes the binder created from the binder menu.

 

DELETE

Remove all binder surfaces and mesh from the database.
